A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Precisely measuring minute ...

For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...

Focused Laser Differential Interferometry (FLDI) is an innovative, non‐intrusive optical diagnostic tool designed to capture high-resolution density fluctuations within hypersonic flow environments.

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

For most of us, the mention of “technological innovation” brings to mind images of the technologies that have become useful for our everyday lives. We imagine aspiring app developers lounging about ...

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

Scientists are building giant space lasers to unlock the secrets of ripples in spacetime. The Laser Interferometer Space Antenna (LISA) will comprise a trio of spacecraft flying in a vast triangular ...

This animation, provided by the Max-Planck Institute for Extraterrestrial Physics (MPE), shows the path of light inside GRAVITY+, an instrument and a large and complex upgrade to ESO’s Very Large ...

6-axis nanopositioning system assembly provides the ultra high precision required to mount and align optical components to be launched into space, new from PI. Image Credit: PI (Physik Instrumente) LP ...

Orbital observatories such as the Hubble Space Telescope and James Webb Space Telescope (JWST) can see far back into the universe—so far, in fact, that they have revealed some of the earliest galaxies ...
